SACRAMENTO – The California Department of Public Health (CDPH) is urging Californians to check their immunization status and get vaccinated against measles after local health departments have notified the state of multiple recent cases of measles. This includes an outbreak of eight related cases in Shasta County, the state’s first measles outbreak since 2020. All of these individuals were either unvaccinated or had an unknown history of vaccination. Last week, CDPH issued a Health Alert notifying health care providers to be on the lookout for measles in patients presenting with a fever, rash and other symptoms consistent with measles.
“As a pediatrician and parent, I encourage families to make sure everyone gets up to date on their MMR vaccine, if they haven’t already,” said Dr. Erica Pan, CDPH Director and State Public Health Officer. “CDPH continues to coordinate with, and support, local health departments in their responses to stop measles from spreading further in our communities. The United States is experiencing the highest numbers of measles cases, outbreaks, hospitalizations and deaths in more than 30 years, driven by populations with low vaccination rates. We all need to work together to share the medical evidence, benefits, and safety of vaccines to provide families the information they need to protect children and our communities.”
Cases have been reported in Los Angeles, Orange, San Bernardino, Riverside and Shasta counties. Two recent cases visited Disneyland on January 22 and 28 while infectious. Local health officials are working with Disneyland Resort to notify potentially exposed employees, and members of the public that visited Disneyland on either date should contact their health care provider if they develop measles symptoms.
As of February 9, 2026, a total of 17 measles cases have been reported statewide. Elsewhere in the United States, one of the largest outbreaks in over 30 years is happening in South Carolina with 920 associated cases.
California reported more than 95% measles, mumps, and rubella (MMR) coverage among kindergarteners for the 2024-2025 school year – the level of immunity needed to reduce the risk of community spread. To continue achieving this level of protection from measles and other preventable diseases, CDPH and the West Coast Health Alliance (WCHA) recently endorsed the 2026 American Academy of Pediatrics Recommended Child and Adolescent Immunization Schedule, ensuring all Californians receive access to evidence-based guidance on life-saving vaccines.

Get Vaccinated
The MMR vaccine provides the best protection against disease and serious illness. It is important Californians check to see that they and their family members are up to date as the number of measles cases has increased. In particular, it’s important that families are up to date on all vaccines before traveling, including international travel and travel to domestic areas where there are measles outbreaks. It is also important to be up to date before visiting places or events where there are many people from other countries or regions of the United States, such as large sporting events, theme parks or airports.
Before traveling internationally, everyone 12 months and older should receive two MMR doses, and babies 6 to 11 months are recommended to get one dose of MMR vaccine. Families with children traveling to regions in the United States with ongoing outbreaks should consult with a health care provider about following immunization recommendations for international travel.
Families can check their vaccination status with the California Digital Vaccine Record (DVR) and schedule a vaccine appointment by visiting MyTurn.ca.gov, or contacting their local pharmacy or health care provider. MMR vaccines are covered for most people through their health insurance plans, including Medi-Cal and regular health care providers. People having difficulty obtaining vaccines can contact their health care provider or local health department for help finding a place to get immunized.
About Measles
Measles is a highly contagious viral disease. Unvaccinated individuals, particularly young children and pregnant people, face the highest risk of severe illness and even death. Roughly 90% of those unvaccinated and exposed to measles will contract the disease. Symptoms include a fever that lasts a couple of days followed by a cough, runny nose, conjunctivitis (pink eye) and rash. Those infected can spread measles about four days before their rash starts to four days afterwards.
Measles remains common globally, including in Europe, Africa and Asia. There are also ongoing outbreaks in Canada and Mexico. Although the United States eliminated measles in 2000, cases have risen, with major outbreaks in Texas and South Carolina in 2025. California experienced a notable outbreak linked to Disneyland from December 2014 to April 2015, infecting 131 residents and others in six additional states, Mexico, and Canada. Due to California’s currently high levels of immunization, the state is less likely to see sustained transmissions as has been seen in other states in recent years. However, transmission of measles is still possible, particularly in communities with lower immunization coverage.
